Cleveland C55136 Straight Flute Hand Tap

The Cleveland C55136 is a straight flute hand tap designed for creating internal UNC threads in a variety of materials. It suits maintenance technicians and machinists who need to cut 9/16"-12 threads by hand or with a tapping head.

9/16"-12 UNC thread capacity and H3 limits

This tap cuts a 9/16"-12 UNC thread with a 1.66 inch thread length and an overall length of 3.59 inches. The H3 thread limit provides a standard fit for Class 2B holes, while the 75 percent thread drill size of 12.20 mm ensures proper clearance for tapping.

High-speed steel with TiN coating for wear

The high-speed steel body with titanium nitride coating resists wear during repetitive threading operations. The plug chamfer assists alignment when starting threads in through-holes or blind holes with adequate depth. Right-hand cutting direction matches standard fastener conventions.

Questions about this item

Will this 9/16"-12 UNC tap work with my existing 12.20 mm drill bit for 75 percent thread engagement?

Yes, the 12.20 mm drill size listed matches the 75 percent thread engagement specification for this tap.

How can I confirm the H3 thread limit is cutting correctly after setup?

Check the finished threads with a 2B class-of-fit gauge; the H3 limit is designed to produce a 2B fit.

Does the box include a tap wrench or only the TiN-coated HSS tap itself?

Only the straight-flute hand tap is supplied; a tap wrench must be purchased separately.
